Synthetic Printing Thickener
FSX Chemical supplies HV, MV and LV sodium alginate thickeners mainly for reactive textile printing. Grades can be matched by viscosity, solubility and process needs, supporting stable paste preparation, clean printing performance and selected formulation use.
Synthetic Thickeners · Application Overview
How Synthetic Thickeners Support Textile Printing
Acrylic-based liquid thickeners control printing-paste viscosity and flow. Select the grade for pigment, reactive or disperse printing, then assess performance with your fabric and formulation.
Viscosity Build
Develops paste body and allows viscosity adjustment during preparation.
Paste Flow
Controls paste rheology for transfer through flat-screen and rotary-screen equipment.
Print Definition
Supports sharp outlines and controlled spreading in a matched printing formulation.
Screen Running
Supports smooth paste transfer with reduced mesh-clogging tendency under suitable conditions.
Electrolyte Tolerance
YS-3169 offers strong electrolyte tolerance for reactive dye printing pastes.
Wash-Off & Handle
YS-3169 and YS-816 support desizing and soft handle under suitable process conditions.
Three Grades · Three Printing Systems
Pigment Printing
For pigment and binder pastes; stock-paste preparation or direct viscosity adjustment.
Reactive Printing
For cotton and viscose; used as the main thickener or with sodium alginate.
Disperse Printing
For polyester with flat-screen and rotary-screen printing processes.
Application Guide · Printing Workflow
Synthetic Thickeners in the Printing Process
Follow the paste from preparation to the finished fabric. Mixing, fixation and washing requirements depend on the selected printing system.
-
Prepare the Paste
Stir the liquid thickener before use. Incorporate it under effective mixing, following the selected grade’s preparation sequence.
-
Adjust the Formulation
Mix the colorants and required auxiliaries. Adjust dosage to target paste viscosity and check uniformity before printing.
-
Screen Printing
Check paste transfer, screen running and pattern edges on the actual fabric at the intended machine speed.
-
Dry & Fix
Follow the binder’s curing conditions for pigment printing, or the dye system’s fixation conditions for reactive and disperse printing.
-
Wash Where Required
For reactive and disperse printing, follow the specified wash-off process. Conventional pigment printing generally does not require post-print washing.
-
Review the Finished Print
Check color yield, print definition and fabric handle after the required treatments. Record results for production approval.
Application Trials · Print Performance
Evaluate Synthetic Thickener Printing Performance
Compare paste behavior and finished fabric when evaluating synthetic thickeners for pigment, reactive or disperse printing. Record the formulation, working dosage and process conditions for each trial.
Six Checks for Your Printing Trial
Use your current thickener as the reference and compare the following results under matched conditions.
Paste Stability & Compatibility
Measure viscosity at consistent intervals. Check for separation, particles or viscosity changes after adding colorants and auxiliaries.
Screen Transfer & Flow
Observe paste transfer, screen release and mesh build-up during flat-screen or rotary-screen printing at the trial speed.
Print Definition
Compare fine lines, sharp edges and solid areas. Check bleeding, uneven coverage and penetration on the selected fabric.
Color Yield & Uniformity
Compare shade depth and evenness at the same colorant level, fabric and fixation conditions, including any required washing.
After-Treatment & Handle
For reactive and disperse prints, assess wash-off and background clarity. For pigment prints, assess handle after binder curing.
Repeatability & Cost-in-Use
Repeat the trial to check consistency. Compare thickener cost at the dosage needed to achieve an acceptable print result.

Match the Preparation Method to the Grade
FSX synthetic thickeners are acrylic-based liquid grades for textile printing paste. Use the preparation method for the selected product; one mixing sequence does not cover every pigment, reactive and disperse formulation.
FSX 5112 · Pigment printing. For stock-paste preparation, add gradually to water under high-speed stirring. Direct viscosity adjustment is another TDS-listed route, with the addition level evaluated in the pigment and binder formulation.
FSX YS-3169 · Reactive printing. Follow the specified sequence for water and auxiliaries. Where sodium alginate is included, complete its prescribed mixing stage before adding YS-3169, then follow the TDS mixing and aging guidance.
FSX YS-816 · Disperse printing. Stir before use and follow its TDS for incorporation. Evaluate working dosage and paste viscosity for the intended flat-screen or rotary-screen polyester printing process.
